A vulnerability was found in cups-filters. This security flaw occurs if you use beh to create an accessible network printer, possibly resulting in remote code execution.

Incomplete blacklist vulnerability in util.c in foomatic-rip in cups-filters 1.0.42 before 1.4.0 and in foomatic-filters in Foomatic 4.0.x allows remote attackers to execute arbitrary commands via a ; (semicolon) character in a print job, a different vulnerability than CVE-2015-8327.

Incomplete blacklist vulnerability in util.c in foomatic-rip in cups-filters 1.0.42 before 1.2.0 and in foomatic-filters in Foomatic 4.0.x allows remote attackers to execute arbitrary commands via (backtick) characters in a print job.

An integer overflow flaw leading to a heap-based buffer overflow was discovered in the way the texttopdf utility of cups-filter processed print jobs with a specially crafted line size. An attacker being able to submit print jobs could exploit this flaw to crash texttopdf or, possibly, execute arbitrary code with the privileges of the 'lp' user.

The removebadchars function in utils/cups-browsed.c in cups-filters before 1.0.66 allows remote IPP printers to execute arbitrary commands via consecutive shell metacharacters in the (1) model or (2) PDL. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2707.
